    Anti-Vibration System
    STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

    IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.
  • Zoom
    Ematic™ Lubrication System
    The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.

Rated 1 out of 5 by from Lasted two days... Bought this to cut up some firewood occasionally. Used it the day i bought it for about an hour. Next day wouldn't start. Took it back to where I bought it the repair guy there had no clue what was wrong with it or how to fix it, had to exchange my saw and send mine out to stihl. Can't believe a chain saw would only last two days and have to be went out to stihl. I am disappointed in this product immensely. Hopefully the one I have now lasts more than this one.

Rated 1 out of 5 by from won't even crank - several things wrong out of the box Has not cranked since I brought it home new from the store. I thought you guys prided yourself on quality? New out of the box this product was in horrible shape. Chain so loose the dealer had difficulty tightening it. Handle appears loose and weak. At the store even the plastic cover on the blade was broken and I had to beg the dealer for a new one. This is the worst buying experience in years.

Rated 5 out of 5 by from Stihl Products are the best! I needed a good saw for a medium size tree that fell during a storm. I decided to go with something good to have for future use and mabee some tree work for friends and family. I decided to buy the MS170 and I was not disappointed. All the best saws I have ever used were Stihls. I love Stihl products and have been a Stihl fan for a long time and I have tried a lot of brands as I used to work for a lawn care company for 4 years and Stihl was always the best. I am very happy with this saw and plan on buying everything I can from Stihl.

Rated 5 out of 5 by from Great saw! Easy to handle. Easy to start and maintain. Well balanced for ease of use. A little on the weak end of the power spectrum, but to be expected for the model and size. Great value and quality for a home use saw.

Rated 5 out of 5 by from I've been educated! I've owned a lot of chainsaws in the past but never a STIHL. After using this, I'll never own another brand again. What a difference.
